Naruto would gain Frieza's power of flight. This would be a new addition to his skill set. Also, his regenerative abilities could be enhanced similar to Frieza's. If he gets injured in battle, he would be able to quickly heal himself. His new form might also give him the ability to survive in harsh environments, like the vacuum of space which Frieza can do.
Naruto could also develop a zanpakuto - like weapon. Since he is known for his summoning jutsu, his zanpakuto could have the ability to summon different Espada - themed creatures. These creatures could assist him in battle, much like how his shadow clones help him currently.
Naruto could inherit Frieza's ability to survive in space and extreme environments. Along with that, his Rasengan could take on new forms influenced by Frieza's energy. For example, it could be a purple - colored Rasengan with the destructive power of Frieza's attacks. He may also gain the power to transform like Frieza, with each transformation increasing his strength, speed, and overall combat capabilities.
Well, he might gain the power of creation. As a primordial god, Naruto could create new worlds or dimensions. He could also have the power to manipulate time, perhaps stopping it or reversing it in certain areas. And of course, his physical strength would be on a whole new level, able to effortlessly destroy mountains with a single punch.
Well, it would be really interesting. Frieza's training might focus on making Naruto more ruthless in combat. Naruto has always been about protecting his friends and his village, but Frieza's training could introduce a more cut - throat approach. Also, Naruto could learn how to better control his power surges. Frieza has experience with handling large amounts of power, so he could teach Naruto to not overexert himself and be more strategic in using his strength.
He might gain enhanced physical strength like Bane. Bane was known for his brute force, so Naruto could have a similar boost, being able to overpower his opponents more easily in hand - to - hand combat.
In this fanfiction concept, Naruto's powers would be a blend of his own and what he could inherit from Itachi. Since Itachi was a very powerful ninja, Naruto might have an innate ability for genjutsu, which was one of Itachi's strong suits. His chakra control could be improved due to his Uchiha blood. And with the Sharingan, he might be able to use Susanoo in the future, although it would probably be a different form compared to Itachi's, as Naruto also has the Nine - Tails' chakra. This combination of powers would make him an extremely formidable ninja.
His shadow clone jutsu would have great potential in the High School DxD world. He could use it for reconnaissance, sending clones to gather information about the various factions. Also, Naruto's sage mode could give him an edge in combat. He might be able to sense the presence of different supernatural beings more acutely. Since his powers are based on his own physical and mental training in the Naruto world, he would need to learn how to use them in a world where there are different power structures like sacred gears and peerages.
If Naruto were in Frieza's body in fanfiction, it could lead to some interesting power dynamics. Naruto is used to his own set of chakra - based powers, but now he has Frieza's immense strength. He would probably struggle at first to control Frieza's body and its abilities. However, his indomitable spirit would likely drive him to master it quickly. He could then use Frieza's reputation to his advantage, perhaps surprising his enemies in the Dragon Ball world who expect the same old evil Frieza.
His powers would be a mix. He would still have his chakra - based ninja powers like the Rasengan and shadow clones. But he might also have access to Batman's high - tech gadgets. For instance, he could attach explosive tags to Batman's batarangs. His chakra could also be used to power up some of Batman's vehicles, making them faster or more stealthy.
Well, considering his parentage, Naruto's powers would be a unique blend. Nagato's powers are mainly centered around the rinnegan, which includes things like the ability to absorb chakra and use various path - related abilities. Now, if we add Serafall's influence, he could have some sort of magical enhancement to his physical abilities. He might be able to run faster or jump higher with a touch of magic. Also, his rasengan could be infused with magic, making it even more destructive. His powers would not only be about raw strength but also about the versatility that comes from combining ninja and magical abilities. He would need to train hard to master these powers and use them in a way that is beneficial for the world around him rather than causing chaos.
